这是一个简易的可以旋转的自定义ViewGruop，可以自定义Interpolate来做变速旋转。

首先在项目的 build.gradle->allproject->repositories中加入:
    allprojects {
        repositories {
        maven { url 'https://jitpack.io' }
    }
}
然后app的build.gradle->dependencies中加入:
    compile 'com.github.chenxin185:3dViewAndroid:1.0.2'

 <com.xingmeng.chenxin.my3drotateview.My3dRotateView
    android:id="@+id/mView"
    android:layout_width="match_parent"
    android:layout_height="300dp"
    app:childHeight="50dp"
    app:childWidth="50dp"
    app:margin_ovalHeight="100dp"
    app:margin_ovalWidth="50dp">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@mipmap/ic_launcher" />

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@mipmap/ic_launcher" />

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@mipmap/ic_launcher" />

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@mipmap/ic_launcher" />
    
</com.xingmeng.chenxin.my3drotateview.My3dRotateView>

    my3dView = (My3dRotateView) findViewById(R.id.mView);
    //Item的点击事件
    my3dView.setItemClickListener(new My3dRotateView.OnItemClickListener() {
        @Override
        public void onItemClick(View view, int position, boolean isFirst) {
            Log.e("infoo","onItemClick position = "+position);
        }
    });
    //自定义的插值器，返回的是每一帧改变的角度
    my3dView.setInterpolate(new My3dRotateView.My3dInterpolate() {
        @Override
        public double getInterpolation(float timing) {
            return 0;
        }
    });
